A line adds up to equal 180 degrees. And adjacent angles also add to equal 180 since they share a side on a line. So add them together and make them equal 180
9x - 7 + 8.5x + 4 = 180
17.5x - 3 = 180
17.5x = 183
x = 10.5
Answer:
1. 6
Step-by-step explanation:
500 – 350 = 150
150/25 = 6
Rearrange the product
(5.91 * 10^(-3)) * (8.7 * 10^10)
as
(5.91 * 8.7) * (10^(-3) * 10^10)
We have 5.91 * 8.7 = 51.417, and 10^(-3) * 10^10 = 10^(10 - 3) = 10^7, so the original product above reduces to
51.417 * 10^7
We can "add" powers of 10 by moving the decimal place to the left:
51.417 = 5.1417 * 10
so that
51.417 * 10^7 = (5.1417 * 10) * 10^7 = 5.1417 * 10^8
